Description

This application can be used to fully control a miniVNA Vector Network Analyzer. Is still in beta so your feedback is essential to make it better. Current version has the following features:

- fully control the data acquisition from a miniVNA, with or without the Extender;- work over USB, bluetooth or WiFi (if available);- support for all Smartphones and Tablets with a resolution higher than 320x240, based on Android version 2.2 or higher;- can display reflection data in rectangular or Smith Chart mode;- intuitive and wizard based calibration interface to speed up the calibration procedure;- calibration data is saved in the configuration file for each mode (Antenna/Transmission/Frequency), so no need to repeat the procedure each time you start the application;- if no calibration data is available at startup, calibration procedure is initiated automatically;- offline mode support allows you to load and/or save vectorial data without connecting to a miniVNA. This mode can be used to play with all the features available for both Standard and Pro versions. Some sample files are included in the package;- internal Smartphone memory is used if no SD card available;- export data in CSV, ZPLOTS or S1P formats compatible with many existing applications;- save PNG screenshots;- demo capture file included to be able to play with the application even without a VNA;- virtual LED to display current connection mode: BLUE – Bluetooth connected, YELLOW – BT connection in process, RED – Error connecting over Bluetooth, GREEN – Offline Mode;- automatically enter Offline Mode at startup if Bluetooth is disabled;- antenna (reflection) and Transmission modes support with the following features:- gesture (Multi Touch) support for horizontal zoom and frequency shift without a new capture;- parameters that can be measured : SWR, |Z|, Return Loss, Phase, Rs, |Xs| for miniVNA and signed Xs for miniVNA Pro;- you can select one of the predefined bands (all HAM bands), HF (0.1 – 30MHz), or a custom frequency interval (anywhere between the frequency range of the connected analyzer);- select parameter to display (using different colors);- an on screen marker can be activated / deactivated and freely moved by dragging it around the screen;- display all the parameters values at the marker position (only the ones you manually selected);

Frequency generator mode with the following features:- 2 independent channels (for miniVNA pro) or 1 channel (for miniVNA standard);- normal or sweeper mode;- independent attenuator control per each channel (from -60dB to 0dB), only for miniVNA Pro;- adjustable phase difference between the channels (0-180 deg);- extremely easy AND intuitive operation, even with small screen devices;- possibility to manually enter the frequency through a numeric keypad;- working in manual frequency set OR continuous (live) mode;- rotary knob to change parameters in both manual or live modes. The knob provides acceleration;- lock mode to prevent accidentally settings changes;- frequency calibration can be done in a very intuitive mode from Generator mode.

Cable data mode with the following features:- background control graphs for Phase and Loss, calculation is done automatically;- just connect the cable to be measured at the DUT connector with the other end open;- include a list of well-known coax cables and their Velocity Factor;- measure and calculate cable length from less than 1m to hundreds of meters;- cable length is measured in 2 steps, for a better precision (second step reduce the frequency interval);- operate in meter or feet mode;- measure cable loss for different frequencies from 0.1 To 180/200 MHz;- can work in Offline mode, if the cable was measured before and data saved in a file.

Recent changes:Changes in 0.9.6-3: - full screen (immersive mode) with Android >= KitKat - navigation buttons are now hiddenSolved bugs: - Bluetooth broken again in Android 6. Add back ACCESS_COARSE_LOCATION permission as this is required for Bluetooth discovery - files saved with version < 0.9.5-1 are loaded incorrectlyApp forum:http://www.yo3ggx.ro/forum/viewforum.php?f=4

Please send me a mail if you have any issue with the application before giving a low rating in Play Store. Thank you. Dan
